'serial no. 504,283.

This invention relates to bin gates, and while not limited thereto relates more speciiically to a shuiiie feeder gate for controlling the feed ofcokeandiother similar material from storage binsA and the like, and has for its object the provision of an improved structure of this class which will be simple in operation and will provide a constantly measured feed of the material from the bin.

In the drawings:

. Figure 1 is a side elevation of a'bin 7and shuiiie feeding mechanism constructed in accorda-nce with this invention.

Figure 2 is a fragmentary sectional plan Figure 1.

Figure 3 is a rear endelevation of the apparatus of Figure 1.

Referring more particularly to the drawings, the numeral 2 designates the lower portion of a material storage bin, the side walls -of which are inclined downwardly and in'- wardly and the lower end of which is open to permit the discharge'of the material from the bin. An arcuate shaped gate member 3, having side members 4, is provided for normally closing the 'discharge opening at the lower end of the bin 2. The side members 4 of the gate 2 extend upwardly along opposite sides of the bin 2, and are pivotally con- Vnected tosupporting members 5 secured "to the bin at one side of the center line of said bin. vThe forward side wall of said bin, that the point of connection gate, has its lower portion cut away additional discharge space for the gate, and sai-d to be closed by which is adaptmaterial passing onto said cut away portion is adapted an adjustable plate member 6 ed to be regulated toward and gate member 3 to regulate the iiow of material onto the gate. The rear side wall of the bin 2 is provided with a wearplate Z which projects downwardly closely adjacent the gate.v

An elevator hoot 8 is positioned below the lower end of the bin 2 and is adapted to have the lower end of an endless bucket conveyer 9 positioned therein. The conveyer 9 is trained over tail pulley 1() within the boot 8, which pulley is mounted on a shaft 12.

away from the InA order to rock orshift the gate 3,y about its pivotal connection with the brackets 5,

a crank arm 13 is secured to' 'theftail shaft` 12 of the conveyer 9, and this crank arm 13 is connected to the gate 2 by `a' connectingrod 14e.v

In operation, when the elevator 9 isset in motion the crank arm 13 will be rotated and motion will be imparted to the gate 3 through I the connecting-rod 14 Soas to shift or rock the gate 3 about its pivotal mountings and cause the material deposited on the gate from thebin to flow out by lateral displacement. f

As the material is forced over the edge of the gate 3 it will be deposited in the oncoming bucket of the conveyer 9. A certain amount of spillage will take place and the material spilled is allowed to accumulate in the elevator boot 8 until there is a sufficient Y quantity of material collected in the chute for the oncoming buckets to pick up as they pass around the tail pulley 10.

Due to'the'particular mounting of the gate 3 at a bin 2, it is unnecessary to uncover the open lower end of the bin in order to permit a measured discharge of the material from the bin.l Therefore, this gate may be readily operated to discharge measured quantities of the material without any danger of pieces of the material becoming lodged between the gate and the lower end of the bin as would be the case if the gate were mounted on the center line so as to make it necessary to move the material over the lower edge of the bin in order to get a discharge of materia-l from the bin.l

While one specific embodiment ofvthis invention has been shown and described, it will be understood't'hat the invention is not to be limited thereto, since various modifications may be made without departing from the scope of the invention, as defined inthe apf pended claims.

point forward of the center line of the s shaft adjacent and below the lower end of said bin, an arcuate shaped gate member for controlling the flow of material through said openl lower end of said bin, said gate having side portions extending'upwardly along said bin and pivotally connected to said bin at one side of the center line of said bin, the side wall of said bin nearest said point of connection of said gate having its lower end cut away, an adjustable plate mounted ovei` said cut away portion and adapted to regulate the flow of material through said gate, a wear plate for the other side wall of said bin, a crank arm secured to the tail shaft of said conveyer and a connecting-rod connecting said crank arm and said gate whereby said gate will be rocked to cause a lateral displacement of a regulated quantity of material from said gate onto said conveyer.

2. In combination with a conveyer, a bin having downwardly and inwardly sloping side walls,an arcuate shaped gate member for controlling the How of material through the lower end of said bin, said gate having side portions extending upwardly along said bin andpivotally connected to said bin at one side of the center line of said bin, the side wall of said bin nearest said point of connection of said gate having its lower end cut away, an adjustable plate mounted over said out away portion and adaptedl to regulate the flow of material onto said gate, a wear plate for the other side wall of said bin, a rotating shaft associated with said conveyer, a crank arm secured to said shaft and a connecting-rod connecting said crank arm and said gate.

In testimony whereof, I have hereunto set my hand. ,Y f
